In most industrial plants, robot maintenance is spread across multiple shifts. Yet very few organisations have a solid protocol for passing information from one shift to the next. The result is predictable: symptoms go undocumented, temporary fixes are never recorded, and incoming technicians arrive without knowing the true state of the equipment.
Why the shift handover is a critical moment
An industrial robot sends warning signals long before it actually stops. Unusual vibrations, slightly longer cycle times, alarms that get reset without investigation — each of these is valuable information that, if not recorded and handed over, disappears with the outgoing technician. By the time the next shift spots the problem, the context needed to diagnose it quickly is already gone.
The direct consequence is lost time during diagnosis and, more often than not, a longer stoppage than would have been necessary. In continuous production environments, that cost is very real.
What to record every shift
The goal is not to document everything, but to capture what matters to the person coming in. A useful shift log for industrial robots should include at minimum:
- Status of each robot at shift end: in production, on pause, under maintenance or with an active fault.
- Alarms raised: which ones occurred, whether they were resolved or simply reset, and what was done.
- Interventions carried out: adjustments, lubricant top-ups, consumable replacements, manual resets.
- Symptoms noticed but not resolved: noises, vibrations, irregular behaviour that has not yet triggered an alarm.
- Pending actions: what still needs to be done, how urgently, and whether any specific spare part is required.
- Environmental conditions: temperature, humidity or process changes that may be affecting the robot.
How to structure the handover
Format matters as much as content. A log nobody reads is worthless. Here are the keys to making it work in practice:
Short and structured
A form with predefined fields — whether on paper, in a shared spreadsheet or in a CMMS — reduces completion time and prevents critical information from being skipped. Open-ended free text fields tend to get filled with vague phrases or left blank entirely.
A five-minute handover conversation
A written record does not replace a brief conversation between the outgoing and incoming technician. Five minutes in person or on the phone to go over open items prevents the kind of misunderstandings no form can catch.
Signed acknowledgement
Both the person handing over and the person receiving should be identified in the log. This is not bureaucracy for its own sake — it is the mechanism that ensures both parties pay genuine attention to the handover.
Integration with your CMMS
If your plant already uses a maintenance management tool, shift log entries should feed directly into open work orders. Every symptom noted in the handover is a potential input for a preventive or corrective work order. If you do not have a CMMS, a shared file or even a physical notebook with a standardised format can serve the same purpose at zero cost. What matters is consistency, not the tool.

Common mistakes to avoid
- Logging only breakdowns, not the preceding symptoms.
- Writing "all clear" when there are unresolved minor faults.
- Failing to distinguish between alarms that were fixed and alarms that were simply reset.
- Not recording temporary interventions (a bypass, a parameter changed provisionally).
- Skipping the log when a shift ends in a rush due to a production surge.
Medium-term benefits
A well-implemented handover protocol has effects that extend well beyond the next shift. Over time, the accumulated history makes it possible to spot recurring failure patterns, anticipate spare part needs and plan interventions during scheduled maintenance windows. It is, in short, the foundation on which effective preventive maintenance is built.
If you want to review how your robot preventive maintenance is performing and where the main gaps are, our consultancy and audit service can help you identify weak points without a large-scale project. We also offer maintenance contracts tailored to different coverage levels for plants running ABB, KUKA and FANUC robots.
